In January this year, the new T-HCBS signal jammer system was installed in the Palapana Agrahara Central Prison in Bangalore to combat illegal mobile phone use by prisoners.cell phone jammer Although the internal communications of the prison are effectively controlled, the communications of the surrounding communities have been seriously disrupted, and the daily lives of residents have fallen into chaos.signal jammer

　　Residents' plight and dissatisfaction

　　Akash Sharma, a resident living near the prison, mentioned: "We often don't receive OTPs, deliverymen can't get through the phone, and even the children's school can't contact us in an emergency.

　　Residents have complained to the prison authorities and telecom operators many times, but they have not been effectively resolved. In response, some helpless residents chose to take to the streets to express their dissatisfaction through protests. During the protest on June 10, residents held banners and shouted slogans, demanding that the prison take immediate measures to reduce the coverage of the jammer.

　　Investigation and response from government departments

　　After receiving the complaint, the Department of Telecommunications (DoT) sent technicians to conduct multiple inspections on site in May and confirmed that the prison jammer affected three surrounding signal towers. However, the solution is not easy. "In order to combat the illegal activities of prisoners, we have no choice but to install powerful jammers," said Malini, a prison official. "We will continue to look for technical solutions to minimize interference to surrounding residents."

　　However, despite the authorities' promise to adjust the technology, the formulation of the solution faces a dilemma because the core purpose of the jammer is still to cut off prisoners' communication tools. It is a daunting challenge to prevent prisoners from regaining communication channels while reducing signal interference.

　　Remote work and online education have been impacted

　　In Bangalore after the epidemic, remote work and online education have become the norm for many families. But the presence of jammers has put families living in the affected areas in trouble. Rajesh S said: "My work from home has become a nightmare. Every time I have a meeting, the video is stuck and the call is intermittent. We have changed network providers several times, but it still doesn't help."

　　What is particularly worrying is that students' online learning has also been greatly affected. Parents have said that their children cannot participate in online courses normally, and the quality of education has been seriously affected.
